Boron nitride was first produced in the 18th century and, by virtue of its extraordinary mechanical strength, has found extensive application in industrial processes since the 1940s. However, the more recent discovery that boron nitride allotropes are as structurally diverse as those of carbon (e.g. fullerenes, graphene, carbon nanotubes) has placed this material, and particularly its low-dimensional allotropes, back at the forefront of modern material science. This book provides a comprehensive history of this rapid rise in the status of boron nitride and boron nitride nanomaterials, spanning the earliest examples of three-dimensional boron nitride allotropes, through to contemporary structures such as monolayer hexagonal boron nitride, boron nitride nanomeshes, boron nitride nanotubes and the incorporation of boron nitride into cutting-edge van der Waals heterostructures. It specifically focuses on the properties, applications and synthesis techniques for each of these allotropes and examines how the evolution in boron nitride production methods is linked to that in our understanding of how low-dimensional nanomaterials self-assemble, or ‘grow’, during synthesis. The book demonstrates the key synergy between growth mechanisms and the development of new, advanced nanostructured materials.

Boron nitride (BN) is a synthetic binary compound located between III and V group elements in the Periodic Table. However, its properties, in terms of polymorphism and mechanical characteristics, are rather close to those of carbon compared with other III-V compounds, such as gallium nitride. BN crystallizes into a layered or a tetrahedrally linked structure, like those of graphite and diamond, respectively, depending on the conditions of its preparation, especially the pressure applied. Such correspondence between BN and carbon readily can be understood from their isoelectronic structures [1, 2]. On the other hand, in contrast to graphite, layered BN is transparent and is an insulator. This material has attracted great interest because, similar to carbon, it exists in various polymorphic forms exhibiting very different properties; however, these forms do not correspond strictly to those of carbon. Crystallographically, BN is classified into four polymorphic forms: Hexagonal BN (h-BN) (Figure 1(b)); rhombohedral BN (r-BN); cubic BN (c-BN); and wurtzite BN (w-BN). BN does not occur in nature. In 1842, Balmain [3] obtained BN as a reaction product between molten boric oxide and potassium cyanide under atmospheric pressure. Thereafter, many methods for its synthesis were reported. h-BN and r-BN are formed under ambient pressure. c-BN is synthesized from h-BN under high pressure at high temperature while w-BN is prepared from h-BN under high pressure at room temperature [1]. Each BN layer consists of stacks of hexagonal plate-like units of boron and nitrogen atoms linked by SP2 hybridized orbits and held together mainly by Van der Waals force (Fig 1(b)). The hexagonal polymorph has two-layered repeating units: AA'AA' ... that differ from those in graphite: ABAB ... (Figure 1(a)). Within the layers of h-BN there is coincidence between the same phases of the hexagons, although the boron atoms and nitrogen atoms are alternatively located along the c-axis. The rhombohedral system consists of three-layered units: ABCABC ..., whose honeycomb layers are arranged in a shifted phase, like as those of graphite. Reflecting its weak interlayer bond, the h-BN can be cleaved easily along its layers, and hence, is widely used as a lubricant material. The material is stable up to a high temperature of 2300 C before decomposition sets in [2] does not fuse a nitrogen atmosphere of 1 atm, and thus, is applicable as a refractory material. Besides having such properties, similar to those of graphite, the material is transparent, and acts as a good electric insulator, especially at high temperatures (106 [Omega]m at 1000 C) [1]. c-BN and w-BN are tetrahedrally linked BN. The former has a cubic sphalerite-type structure, and the latter has a hexagonal wurtzite-type structure. c-BN is the second hardest known material (the hardest is diamond), the so-called white diamond. It is used mainly for grinding and cutting industrial ferrous materials because it does not react with molten iron, nickel, and related alloys at high temperatures whereas diamond does [1]. It displays the second highest thermal conductivity (6-9 W/cm.deg) after diamond. This chapter focuses principally upon information about h-BN nanomaterials, mainly BN nanotubes (BNNTs), porous BN, mono- and few-layer-BN sheets. There are good reviews book chapters about c-BN in [1, 4-6].

Carbon and boron-nitride based nanomaterials possess many exciting properties making them suitable for numerous applications spanning from electronics to advanced composites. However, these materials when synthesized often differ significantly from the idealized crystals usually considered theoretically. A thorough understanding of the structure of the materials as synthesized and how the resultant materials can be utilized for specific application purposes is required such that these applications can be effectively realized. To this end, the synthesis and characterization of carbon and boron-nitride based nanomaterials is undertaken with specific application purposes in mind. As a potential scalable synthetic route for graphene, graphene oxide (GO) and reduced graphene oxide are synthesized and characterized using atomic resolution electron microscopy. This elucidates their underlying structures revealing that the reduced form of GO does not resemble pristine graphene. The long-standing debate over the structure of GO is successfully ended with this study given the direct observation of the atomic structure of this material. To develop advanced composite materials, the functionalization of carbon and boron nitride nanotubes is undertaken. The characterization of their functionalization and incorporation within composite materials, specifically within a Kevlar polymer matrix, is presented to allow for the development of composites with significantly enhanced mechanical properties. Given a significant body of theoretical work paired with a single previous synthetic success, the synthesis of boron nitride nanoribbons is outlined. The first scalable synthesis of boron nitride nanoribbons is demonstrated resulting in long, consistent width, narrow, few-layer boron nitride nanoribbons which could be ideal for addressing these theoretical considerations. To establish a method for the synthesis of thin hexagonal-boron nitride (h-BN), the design of a specialized CVD system is described. The material resulting from this system is analyzed with methods including atomic resolution electron microscopy with the results informing future approaches for the synthesis of h-BN. Finally, high surface area boron nitride materials should be promising for hydrogen storage applications, especially if templated with a microporous scaffold. To this end, the first synthesis of a high surface area, microporous boron-nitride material is accomplished and the resultant surface areas of these materials are reported.

Abstract : One and two-dimensional hexagonal boron nitride (h-BN) nanomaterials are wide bandgap semiconductors (~6 eV). This large bandgap is in contrast with their corresponding carbon counterparts, for instance, graphene is metallic while carbon nanotubes are semiconducting or metallic depending upon their tube diameter and chirality. The insulating nature of boron nitride nanotubes (BNNTs) has hindered their application in the electronic field despite the superior physical and chemical properties. Our results have shown that BNNTs functionalized with metallic quantum dots have shown their potential as a tunneling field effect transistors (TFETs) devices. Moreover, BNNTs functionalized with carbon nanotubes (CNTs), and molecular carbon has shown potential as digital switches. In this dissertation, methods of functionalizing BNNTs by metallic quantum dots and carbon nanomaterials are discussed. Furthermore, synthesis of other h-BN nanomaterials has been explored. Using the well-established chemical vapor deposition technique, boron nitride nanosheets (BNNSs) and boron nitride nanoribbons (BNNRs) have been synthesized. Towards the end, an outlook on the synthesis of boron nanomaterial is provided.

This thesis focuses on the growth of a new type of two-dimensional (2D) material known as hexagonal boron nitride (h-BN) using chemical vapor deposition (CVD). It also presents several significant breakthroughs in the authors’ understanding of the growth mechanism and development of new growth techniques, which are now well known in the field. Of particular importance is the pioneering work showing experimental proof that 2D crystals of h-BN can indeed be hexagonal in shape. This came as a major surprise to many working in the 2D field, as it had been generally assumed that hexagonal-shaped h-BN was impossible due to energy dynamics. Beyond growth, the thesis also reports on synthesis techniques that are geared toward commercial applications. Large-area aligned growth and up to an eightfold reduction in the cost of h-BN production are demonstrated. At present, all other 2D materials generally use h-BN as their dielectric layer and for encapsulation. As such, this thesis lays the cornerstone for using CVD 2D h-BN for this purpose.
